Customer Table Booking - Requirement 1  
Your friend has opened up a new restaurant and he finds it difficult to keep track of the tables  
booked by customers. Being an aspirant programmer help your friend with a small application that  
would help him keep track of the tables booked. There are three major domains Table, Customer,  
and Booking. The Table and Customer domain are used to store table and Customer details  
respectively. The third domain Booking is used maintain the booking details of a Customer  
corresponding to a particular table.  
Requirement 1:  
Let’s start off by creating Customer objects and check whether two objects are equal by overriding  
equals method.  
1. Create a Customer Class with the following private attributes:  
Member Field Name  
id  
Type  
Long  
name  
String  
mobileNumber  
birthdate  
String  
java.util.Date  
Double  
Double  
java.util.Date  
Double  
averageSpendAmount  
totalAmount  
dateEnrolled  
rating  
2
3
4
. Mark all the attributes as private  
. Create / Generate appropriate Getters & Setters  
. Add a default constructor and a parameterized constructor to take in all attributes in the  
given order: Customer(Long id, String name, String mobileNumber, java.util.Date  
birthdate, Double averageSpendAmount, Double totalAmount, java.util.Date dateEnrolled,  
Double rating)  
5. When the “customer” object is printed, it should display the following details: [Override  
the toString method]  
Print format:  
Id:"id"  
Name:"name"  
Mobile Number:"mob num"  
Date of Birth:"dob"  
Average spent amount:"avg spent amount"  
Total amount:"total amount"  
Date Enrolled:"date enrolled"  
Rating:"rating"  
6
. Two customers are considered same if they have the same name, mobileNumber,  
andbirthdate. Implement the logic in the appropriate function. (Case –  
Insensitive) [Override the equals method]  
The return type of Equals method is bool(either true or false), If it returns true, then print  
"
Customer 1 is same as Customer 2", else print "Customer 1 and Customer 2 are  
different", That print statement will be present in the main method.  
7. The input format consists of customer details separated by comma in the below order,  
(
id, name, mobileNumber, birthdate, averageSpendAmount, totalAmount, dateEnrolled,  
rating)  
The Input to your program would be details of two customers, you need to display their details as  
given in "5th point(refer above)" and compare the two customers and display if the Customers are  
same or different.  
Create a class named as Main, which contains the main method, all the input, and output operations  
are performed in this method(main).  
Note: There is an empty line between display statements. The empty lines are displayed in the Main  
method.

Customer Table Booking - Requirement 3  
Requirement 3:  
In this requirement, you need to validate the name and age of a customer. Also, you need to  
find if the customer is lucky or not.  
i) The name should contain only alphabets and not numbers or special characters.  
ii) The age is considered valid only if it is greater than equal to 18.(Take the current date as  
"01-01-2018")  
iii) A customer is said to be lucky if the repetitive sum of his mobile number is equal to 1.  
Ex:- Mobile number 9635285233 is lucky.  
step1- 9+6+3+5+2+8+5+2+3+3 - 46  
step 2 - 4+6 - 10  
step 3 - 1+0 - 1  
a)Create a Class Main with the following static methods:  
Method Name  
Description  
This method accepts java  
argument and returns a bo  
Calculate the age and retu  
age of the customer is gre  
equal to 18, else return Fa  
static Boolean validateAge(java.util.Date birth)  
This method accepts a Str  
argument and returns a bo  
the name of the customer

Customer Table Booking - Requirement 4  
Requirement 4:  
In this requirement, you need to sort the list of customers by name, amount or rating using  
Comparable and Comparator interfaces.  
a) Create a Customer Class with the following private attributes:  
Member Field Name  
id  
Type  
Long  
name  
String  
mobileNumber  
birthdate  
String  
java.util.Date  
Double  
Double  
java.util.Date  
Double  
averageSpendAmount  
totalAmount  
dateEnrolled  
rating  
Mark all the attributes as private, Create / Generate appropriate Getters & Setters, Add  
a default constructor and a parameterized constructor to take in all attributes in the  
given order: Customer(Long id, String name, StringmobileNumber, java.util.Date  
birthdate, Double averageSpendAmount, Double totalAmount, java.util.Date dateEnrolled,  
Double rating)  
b) The Customer class should implement the Comparableinterface which sorts the  
customer list based on names.  
c) Write a Comparator class namedAmountComparator implementing Comparator  
Interface. This comparator should sort the customers based on the  
averageSpendAmount.  
d) Write a Comparator class namedRatingComparator implementing Comparator  
Interface. This comparator should sort the customers based on their rating.  
The input format consists of customer details separated by comma in the below order,  
(
id, name, mobileNumber, birthdate, averageSpendAmount, totalAmount, dateEnrolled,  
rating)  
Note: If any other option is selected display "Invalid choice".  
Assume that name,amount spent and rating will be always unique.  
When the “customer” object is printed, it should display the following format  
Print format:  
System.out.format("%-5s %-15s %-15s %-15s %-20s %-15s %-15s %s\n",  
"
Id","Name","Mobile Number","Date of Birth","Average spent amount","Total

Mail Folder - Requirement 1  
You work for a start-up company. The company has been using an outdated mail  
system. Looking at the difficulty in the old system, the management decided to build  
their own mail server. There are two major domains, Mail and Mail Folder. The mail  
details are stored in the mail domain. The mail folder is used to group the emails  
together.  
Requirement 1:  
Let’s start off by creating two Mail objects and check whether they are equal.  
1
. Create a Mail Class with the following attributes:  
Member Field Name  
Type  
id  
Long  
to  
String  
from  
String  
subject  
content  
receivedDate  
size  
String  
String  
java.util.Date  
Double  
2
3
4
. Mark all the attributes as private  
. Create / Generate appropriate Getters & Setters  
. Add a default constructor and a parameterized constructor to take in all attributes  
in the given order: Mail(Long id, String to, String from, String subject,  
String content, Date receivedDate,Double size)  
5
. When the “mail” object is printed, it should display the following details:  
[
Override the toString method]  
Print format:  
Id:"id"  
To:"to"  
From:"from"  
Subject:"subject"  
Content:"content"  
Received Date:"receivedDate"  
Size:"size"  
6
. Two emails are considered same if they have the same to address, from  
address, and subject. Implement the logic in the appropriate function. (Case –  
Insensitive) [Override the equals method]  
The input format consists of mail details separated by comma in the below order,  
(
id,to, from,subject,content,receivedDate,size)  
The Input to your program would be details of two emails, you need to display their  
details as given in "5th point(refer above)" and compare the two emails and display if  
the Mails are same or different.  
Note: There is an empty line between display statements. Print the empty lines in main  
function.  
Display one digit after the decimal point for Double datatype.

Mark all the attributes as private, Create / Generate appropriate Getters & Setters, Add  
a default constructor and a parameterized constructor to take in all attributes in the  
given order: public Mail(Long id, String from, String to, String subject, String  
content, Date receivedDate, Double size)  
b)Create a Class MailFolder with the following attributes:  
Member Field Name  
name  
Type  
String  
mailList  
ArrayList<Mail>  
Mark all the attributes as private, Create / Generate appropriate Getters & Setters, Add  
a default constructor and a parameterized constructor to take in all attributes in the  
given order: MailFolder(String name, List<Mail>mailList). In constructor pass the  
mailList value as an empty list. Only one folder will be present at a time.  
c) Create the following static method in Mail class,  
Method Name  
Description  
public static Mail  
createMail(String detail)  
This method accepts a string which contains mail details separated by c  
Split the details and create a mail object from the details and return it.  
The mail details should be given as a comma-separated value in the below order,

Requirement 3:  
In this requirement, you need to validate the email id. Also, you need to find whether  
the email is spam or not.  
a)Create a Class Main with the following static methods:  
Method Name  
Description  
Validate the email id based on t  
rules given below. Returns true  
if email id is valid else return fa  
static Boolean validateEmailId(String email)  
Checks for the spam domain  
name in the given email id.  
Returns true if the mail is spam  
else returns false  
static Boolean validateSpam(String email)  
b) While validating email id follow the below rules. The format of the email id is given  
below  
username@domain.TLD  
where, TLD - Top Level Domain  
1

7
. After the username special character @ should present.  
. The email domain should contain only alphabets(either uppercase or lowercase).  
. After email domain, a value dot ( . ) should present.  
. The email Top Level Domain should contain only alphabets(both uppercase and  
lowercase) and it should have only 2 to 6 characters.  
Example: alpha_Beta.01@google.com is a valid email id.  
Since the username contain only alphabets, numbers and a special character ( _ and .  
)
, then the @ symbol is present. The domain name should contain only alphabets and  
the symbol dot( . ) and the Top Level Domain have only 3 characters.  
c) While checking for spam follow the below rules,  
If the domain name of the email id is one of the following then it is spam email id.  
advancedpdfconverter, passwordmaster, smartfixer, downloadavideo }  
{
Note: Print "Email is valid" if email is valid else print "Email is invalid". Print "Email is  
spam" if email is spam else print "Email is not spam".

Team - Requirement 1  
It's the month of January of a New Year, and its time for IPL auction. Watching the  
auction taking place you find it difficult to keep track of the players each team has  
picked. Being a techie you decide to create a small application which would help people  
to keep track of the players and team details. There are two major domains Player and  
Team  
Requirement 1:  
Let’s start off by creating two Player objects and check whether they are equal.  
1
. Create a Player Class with the following attributes:  
Member Field Name  
name  
Type  
String  
dateOfBirth  
skill  
java.util.Date  
String  
numberOfMatches  
runs  
Integer  
Integer  
Integer  
String  
wickets  
nationality  
powerRating  
Double  
2
3
4
. Mark all the attributes as private  
. Create / Generate appropriate Getters & Setters  
. Add a default constructor and a parameterized constructor to take in all attributes  
in the given order:  
Player(String name , Date dateOfBirth , String skill , Integer  
numberOfMatches , Integer runs , Integer wickets , String nationality ,  
Double powerRating)  
5
. When the “player” object is printed, it should display the following details:  
[
Override the toString method]  
Print format:  
Name:"name"  
Date of Birth:"dateOfBirth"  
Skill:"skill"  
Number of Matches:"numberOfMatches"  
Runs:"runs"  
Wickets:"wickets"  
Nationality:"nationality"  
PowerRating:"powerRating"  
6
. Two players are considered same if they have the same name, skill, and  
nationality. Implement the logic in the appropriate function. (Case – Insensitive)  
[
Override the equals method]  
The input format consists of mail details separated by comma in the below order,  
name,dateOfBirth,skill,numberOfMatches,runs,wickets,nationality,powerR  
ating)  
(
The Input to your program would be details of two players, you need to display their  
details as given in "5th point(refer above)" and compare the two players and display if  
the Players are same or different.  
Note: There is an empty line between display statements. Print the empty lines in the  
main function.  
Display one digit after the decimal point for Double datatype.  
Sample INPUT & OUTPUT 1:  
Enter player 1 detail:

Validate customer details  
There are always typical human entry errors that need to be validated so that the data saved in  
the system are valid and can be used for later processing. Simple Rules that need to be taken  
care:

parseName ( ):  
The customer name contains first name and last name separated by any “special character”.  
Given a name, display the first and last name.  
Examples of Special character like: ' , ' , '@' , '#' , . . . . . (NOTE: There can be any special  
character).  
isValidEmail ( ):  
Check if the email address entered is valid. A Valid email address would end with 3 domains  
(com, org, net) and would contain a “@”.  
playContactNumber ( ):  
Every contact number would be in the format (ISD Code-STD Code-Number). The size of the  
fields would be (3 digits – 4 digits – 10 digits). Given a contact number, find the sum of last 10  
digits until it reaches to a single digit. Print the digit.  
userLifeTime ( ):  
Given a “createdOn” Date, print number of minutes before which the user was created. Assume  
the current date to be ‘28-07-2017 09:00’.  
Date format : "dd/MM/yyyy HH:mm";  
Example for LifeTime calculation:  
If the createdOn date is "28-07-2017 08:20", then the life time is 40 minutes.

Client Interview Preparation  
You are on the verge of completing your training and being on-boarded  
to your first project. Before on-boarding, you are required to take up a  
client interview. Your academy wants to ensure that you clear the  
interview with flying colors. In a quick brainstorming, they thought  
every project would have an end user (Customer and Address). So they  
decided to frame questions based on these two classes.  
Customer Comparison  
Create a class named as Customer, which contains following private  
variables/ attributes,  
Member Field  
Type  
name  
id  
Long  
name  
gender  
email  
String  
Character (M/F)  
String  
contactNumber String  
Date (time in 24 hrs clock)  
dd/MM/yyyy HH:mm:ss  
createdOn  
Mark all the attributes as private  
Create / Generate appropriate Getters & Setters.  
Add a default constructor and a parameterized constructor to take in  
all attributes.  
When the “customer” object is printed, it should display the following  
details: (override toString method)  
Customer: name  
Customer contact details: contactNumber, email  
Two members are considered same if they have same email and  
contactNumber. Implement the logic in the appropriate function.  
(override equals method)  
Input format:  
By default, there are only two customers. More details in Sample IO.  
Output format:  
If both the customers are same then print "Customer 1 is same as  
Customer 2" without quotes.  
Otherwise, print "Customer 1 and Customer 2 are different" without  
quotes.  
Refer Sample Input and Outputs.  
HINT:  
Please print customer id in the Main class.  
The toString method should print as specified in the problem  
statement [ Name and contact details alone]

Overloading - Payment  
With all the software systems that are being built, one of the widely  
used utilities in the financial sector is payments through various  
channels. The widely used channels are OnlineBanking, CreditCard and  
Wallet. The banks generate revenue by charging a small margin as part  
of the usage. Create a class called PaymentUtil. Overload a method  
“
makePayment” as given below in the specification and calculate the  
total payment amount.  
Create a class named as PaymentUtil, which contains following Overload  
methods,  
No Method Name  
Method Description  
This method calculates the  
total amount (amount +  
service tax amount). Here  
the tax percent gets varied  
depending on the bank.  
Fetch the corresponding  
service tax from a map  
collection by bank name.  
Map<String bankName, Float  
serviceTax>  
public Double  
makePayment(Map<String,Float>  
bankTax,String bankName,Double  
amount)

This map is prefilled. Only  
banks present in the map  
would be part of input.  
public Double makePayment(Double This method calculates the  
amount) total amount (include service  
2
tax and value added  
tax(VAT). First, calculate  
the service tax amount and  
then calculate the VAT  
amount.  
[
VAT % is applied on total  
amount+service tax ]  
This method calculates the  
total amount, which is a  
discount from the amount  
with parameterized discount  
percentage.  
public Double makePayment(Double  
amount, Float discountPercent)  
3
Create the class named as Main, which contains the main method. Input  
and output operations will be done in the main method.  
It calls various methods in PaymentUtil class to perform the task.  
The following data will be placed inside the static block in the Main  
class  
onlineBankingMap.put("ICICI", 4.2f);  
onlineBankingMap.put("IBRD", 3f);  
onlineBankingMap.put("IFC", 4.9f);  
onlineBankingMap.put("HSBC", 3.9f);  
That data will provide in template code.  
Problem Specification:  
Overload a method “makePayment” as given in the specification and  
calculate the total payment amount.  
The bank name is case insensitive.  
The service tax for credit card is 5.2%.  
The VAT for the credit card is 2.3%.  
The discount percentege for Wallet is 20.2%.

Car-Service Management System - Requirement 1  
Your friend, a mechanical engineer is very passionate about cars  
and wants to be an entrepreneur. He decides to start his own car  
service center and with his knowledge about cars has the  
capability to service all different brands of cars. You are also very  
keen to help him out in any means possible.  
One fine day, your friend approaches you to help him setup and  
automate the process of tracking various customers and their  
service feedbacks. You decide to quickly build a small system to  
solve the problem.  
Based on the class diagram given below, you start to build a  
prototype of the application.  
Requirement 1:  
td p { margin-bottom: 0cm; direction: ltr; color: rgb(0, 0, 10); text-  
align: left; }td p.western { font-family: "Liberation Serif",serif; font-  
size: 12pt; }td p.cjk { font-family: "Droid Sans Fallback"; font-size:  
12pt; }td p.ctl { font-family: "FreeSans"; font-size: 12pt; }p {  
margin-bottom: 0.25cm; direction: ltr; color: rgb(0, 0, 10); line-  
height: 120%; text-align: left; }p.western { font-family: "Liberation  
Serif",serif; font-size: 12pt; }p.cjk { font-family: "Droid Sans  
Fallback"; font-size: 12pt; }p.ctl { font-family: "FreeSans"; font-  
size: 12pt; }a:link { }  
Let’s start off by creating a customer class based on the below  
mentioned specifications.  
a. Create a Customer Class with the following attributes:  
Member Field Name  
customerId  
firstName  
lastName  
gender  
email  
Type  
Long  
String  
String  
String  
String  
String  
String  
phoneNumber  
address  
b. Mark all the attributes as private  
c. Create / Generate appropriate Getters & Setters  
d. Add a default constructor and a parameterized constructor to  
take in all attributes in the given order: Customer(Long  
customerId, String firstName, String lastName, String gender,  
String email, String phoneNumber, String address)  
e.  
When the “customer” object is printed, it should  
display the following details: [Override the toString method]  
Print format:  
Customer:firstname,lastname  
Contact details:phoneNumber,email,address  
f.Two customers are considered same if they have the same name  
(both firstname and lastname), email and phone number.  
Implement the logic in the appropriate function. (Case –  
Insensitive) [Override the equals method]  
The Input to your program would be details of two customers, you  
need to display their details as given in "requirement e" and compare  
the two customers and display if the customers are same or unique.  
Sample INPUT & OUTPUT 1:

Car-Service Management System - Requirement 3  
There are always typical human entry errors that need to be validated so that the data being saved in the  
system is valid and can be used for later processing. Lets define some simple rules so that data being  
collected are valid.  
Create a class named as Main, which contains following static methods.  
a) Create a method validateLicenceNumber(String licenceNumber) which takes a license  
number(String) and returns boolean (true or false),based on the below rules.  
A licence Number is valid if all the below rules are true.

4
7
chars-state name. ( 2 characters A to Z)  
numbers-branch code (integers) - valid range between 10 - 50  
numbers-licence issued year - valid range between - (2005 to 2016) inclusive of both years.  
numbers -profile id (Any digit should not contain 0).  
eg:MH1420116662821 is a valid licence number.  
b) Write a method isExperiencedDriver(String licenceNumber) which takes a license number(String)  
and returns a boolean.  
This function checks for experience of a driver with respect to licence Number. The year of the  
licence issue starts from 5 th chacter (yyyy determines the year).  
If year of license issued is equal to or greater than 5 years from current year then return true  
,
else return false. Assume today’s date as 28-11-2017. If the method returns true, then the  
driver is termed as experienced. If its less than 5 years, then print as Not Experienced Driver.

Requirement 5:  
a) Create a Customer Class with the following attributes:  
Member Field Name  
customerId  
firstName  
lastName  
Type  
Long  
String  
String  
String  
String  
String  
String  
gender  
email

b) Mark all the attributes as private  
c) Create / Generate appropriate Getters & Setters  
d) Add a default constructor and a parameterized constructor to take in all attributes in the given order: Customer(Long customerId, String firstName, String  
lastName, String gender, String email, String phoneNumber, String address)  
e) A valid email has an @ and ends with “.com / .org”.  
Create a method validateEmail in customer class with return type as void and check for valid email . During the parse, if an email id is invalid, Raise the custom  
exception(InvalidEmailException) and dont add the customer into the list. Print messege "Invalid Email for the user" for the exception.  
f) Write a Comparator class named CustomerComparator implementing Comparator Interface. This comparator should sort the customers based on firstname.  
After reading all the inputs, Apply the comparator on the inputlist read and display the result.  
The output format should be System.out.format("%-5s %-15s %-15s %-15s %-15s %s\n","Id","First Name","Last Name","Gender","Email","Phone");
